(ANTI-ALLERGIC FILTER WHICH CAN BE EXPECTED ITS LIFE TIME) AND ANTI-ALLERGIC FILTER WITH ANTI-

The present invention relates to a method for preparing an anthocyanin-containing composition, comprising: coating and drying a surface using an indicator aqueous solution containing anthocyanin; Treating the surface with a base so that the surface is basic; And a surface treating the surface to include a porphyrin: and a metal phthalocyanine complex. The present invention relates to an anti-allergy filter capable of providing a service life including a nonwoven fabric substrate.

Recently, the air cleaner is being spotlighted in that it keeps indoor air clean by removing dust and odor. These air purifiers visually display the current air pollution, dust and odor removed from the display. In addition, the present air pollution degree is divided into different lighting colors such as clean, low pollution, heavy pollution, high pollution, and so on. In addition, the air purifier uses a plurality of filters for air purifiers having various materials and structures in accordance with their functional requirements, and the filters for the air purifiers must be periodically replaced according to their lifetime. In particular, in order to confirm the replacement cycle of the filter for the air cleaner according to the life of the anti-allergic filter, in the past, it has been necessary to directly visually confirm the degree of contamination due to dust and directly determine the replacement cycle. However, this method is inaccurate, and there is a problem that the cost is wasted by replacing the anti-allergy filter even though it has a longer life.

Therefore, there is a need for a technique that can more accurately determine the life span and replacement timing of the anti-allergy filter.

However, in the known method, it is troublesome to separately manufacture the carrier carrying the indicator and to install the indicator including the indicator separately in a part of the filter. In addition, when introducing such an indicator into the front surface of the filter, the content of components such as activated carbon, which performs the function of the filter, is relatively reduced, thereby deteriorating the performance of the deodorizing filter for the air purifier. In addition, the size of the carrier is so large that it is difficult to apply it to an anti-allergy filter having a nonwoven fabric substrate.

Therefore, there is a need for a technique that can more accurately determine the lifetime and replacement timing of the anti-allergy filter by a simpler method, and does not deteriorate the performance of the anti-allergy filter. Further, there is a need for a technique that can be easily applied to an anti-allergy filter having a nonwoven fabric substrate.
